Value
A list containing the following elements:
- retval
- [
GFileIOStream] a GFileIOStream for the newly created file, or NULL on error. error- return location for a
GError, or NULL
Details
By default files created are generally readable by everyone,
but if you pass G_FILE_CREATE_PRIVATE in flags the file
will be made readable only to the current user, to the level that
is supported on the target filesystem.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If a file or directory with this name already exists the G_IO_ERROR_EXISTS
error will be returned. Some file systems don't allow all file names,
and may return an G_IO_ERROR_INVALID_FILENAME error, and if the name
is too long, G_IO_ERROR_FILENAME_TOO_LONG will be returned. Other errors
are possible too, and depend on what kind of filesystem the file is on.
Note that in many non-local file cases read and write streams are not
supported, so make sure you really need to do read and write streaming,
rather than just opening for reading or writing.
